How is REF615 generated?

The ABB production department implements rigorous and comprehensive control over every stage of the production process, ensuring consistent quality, operational efficiency, and adherence to the highest international standards at all times.

fluorescent optical fiber temperature device

The fluorescent optical fiber temperature sensor works by detecting how a material’s fluorescence lifetime changes with temperature—excited by light, it emits fluorescence, and measuring its decay time gives precise temperature readings. Sensing performance, widely used in biodetection and environmental monitoring fields

Hirschmann Industry Switch

The Hirschmann RSPE35 is a rugged industrial gigabit switch engineered for harsh environments.

Under Frequency Load Shedding (UFLS)

UFLS is a critical protective mechanism in power systems that prevents blackouts by automatically shedding predetermined load blocks when frequency drops due to generation-load imbalance. Using relays and circuit breakers, it acts as a last resort to stabilize frequency and avoid system collapse, ensuring reliability and preventing cascading failures.

symmetrical components

In three-phase power systems, imbalance is caused by faults, uneven loads or equipment problems Question caused. Symmetric component method analysis: positive sequence indicates normal operation, three-phase Equal amplitude and mutual difference of 120 ° rotate in the same direction; Negative sequence triple equal amplitude counter-rotation, It is caused by asymmetric fault, causing the equipment to heat up; Zero sequence three identical phases, Common in ground faults, affecting protection and safety.

Arc Flash Detection System

The arc detection system mainly consists of an arc monitoring unit, a control unit, an optical detector .It consists of a detector, a current detector and a current transformer. Control unit receive .High sensitivity optical signal and current signal, quickly and reliably judge whether to trigger Circuit breaker. Optical fiber has high-speed transmission and anti-electromagnetic interference characteristics, which is reasonable . Imagine signal transmission medium. Light sensor collects arc through bare fiber loop Light is transmitted to the receiver through the optical fiber and converted into an electrical signal to inform the control system System to achieve instant response.

Protection Relay can be adjusted to 100V or 400V

The multifunctional protection relay can adapt to 100V or 400V according to the site. It is convenient to adjust it.

When device no power, get the configuration process

when the device no power, we only put the usb in the front, run the HSPC software, it is easy and convinent.
